A User's Guide to DRM in Online Music

“There is an increasing variety of options for purchasing music online, but also a growing thicket of confusing usage restrictions. You may be getting much less than the services promise. […] In […] this brave new world of “authorized music services,” law-abiding music fans often get less for their money than they did in the old world of CDs (or at least, the world before record companies started crippling CDs with DRM, too). Unfortunately, in an effort to attract customers, these music services try to obscure the restrictions they impose on you with clever marketing.”
